Abstract

The angular distributions of fragments and the fission cross section of ²³⁷Np by neutrons in the energy range from 0.3 MeV to 500 MeV were simultaneously measured using the neutron time-of-flight spectrometer GNEIS at the Petersburg Nuclear Physics Institute, National Research Centre “Kurchatov Institute.” This paper presents a brief description of the experimental setup and compares the data obtained with the results of experiments performed earlier.
